We are an ASP.NET shop, so it is fitting that we use Visual Studio. The biggest advantage that VS gives us is the first-class debugger, and the ReSharper refactoring tools. We do use Sublime, Brackets, Vim, Emacs, and other editors in conjunction with VS since VS does can take a long time to load.

An IDE which I use for at least ten years now. Roslyn is getting better and better, but VS Code seems better now. A bit obsolete concept, but the extra tools (like git integration, azure browsing, preset projects and solutions) makes it still very useful.
